Hi

Just got my decat down pipe put on today, i have always thought there was two sensors on the down pipe, one at the top of the pipe and the other one at the botton (cat pipe) but when it was put on today the mechanic couldn't find the one at the top . was i wrong in thinking there was two ? also i havent had the CEL light come ?? oh it's a 04WRX

Thanks in advance
